Elevio

Security checks for vulnerabilities and agentic risk

Overview

The Elevio features are appropriately scoped, but setup directs the agent to run unverified downloaded software without a clear approval step.

Review the CLI installation before enabling this skill. Prefer a verified, fixed release installed with your approval, and check whether it installs or updates other agent skills. Elevio requests use your OOMOL-connected account. The full bundled artifact was inspected, but the remote installers and hosted service implementation remain unverified; no malicious behavior was established.

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs
Vulnerability Patterns
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • Output HandlingUnvalidated Output Injection, Cross-Context Output, Unbounded Output
  • MCP Tool PoisoningHidden Instructions, Unicode Deception, Parameter Description Injection
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
98% confidence
Finding

The supplied chunk performs remote script execution rather than searching or reading Elevio data. Nothing in the supplied content establishes this Oomol installer as a supporting dependency for Elevio access. The downloaded script's contents are not provided, so its further actions cannot be determined.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

Piping the HTTPS response directly into bash executes mutable remote content without verifying its integrity or reviewing it first. HTTPS protects transport but does not protect against compromise of the distribution endpoint, which could lead to credential theft or host modification under the executing account. This is the same underlying installation risk highlighted by SQP-2, not a separate exploit chain.

Fallback setup executes remotely downloaded installation scripts without a safety warning or user approval.

Medium
Category
Output Handling
Confidence
96% confidence
Finding

The fallback directs an agent to execute downloaded shell or PowerShell code without explicit approval or integrity verification. A request to read Elevio data does not inherently authorize installing software on the host, and a compromised installation endpoint could execute arbitrary code with the agent process's privileges. The missing-CLI condition limits exposure but does not make this installation safe.

Autonomous Decision Making

Medium
Category
Excessive Agency
Confidence
80% confidence
Finding

Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
